2006 Ford Taurus Question: Hard to start and Check light on

Hello, I had a ford escort 98, long story short, i had to get a new car, Ford Taurus 06, It ran smooth and much nicer than my last car. A couple of days ago my engine light came on. Also to add, i noticed that sometimes it has a hard time starting, i have to turn the key twice for it to start. Took it to Autozone to see what the codes are and I got back P0300 (random Missfire) and P0303 (Misfire on Cylinder #3). I'm not that well versed with cars so before i throw money on parts that i don't need can you point me in the right direction as to what could be the most probable problem. I did change out the spark plug but of course, no change, light is still on. I was going to buy some spark plug wires and if that didn't work, the coil packs, however again i don't want to just throw many into parts that i may not need. Thanks

Have Battery checked. My 2006 was doing weird things during start. Did not notice that it was slower to turn over untill battery was replaced. Now turns over fasrer and starts right up. No more weird things happening with dashboard readouts.
